Patented Nov. 12, 1929 UNITED STATES- GEORGE LASKER, OI CHICAGO, ILLINOIS WEATHER-STRIP SUPPORT Application filed April 17, 1929. Serial No. 355,314.

My invention relates to improvements in supports for weather strips and more particularly it relates to weather strip supports suitable for use upon casement and other metal windows of the swinging sash type, as well as for use with doors and for simila purposes. I

' Metal window frames and metal sash frames are usually constructed of rolled sections. The edges of such rolled sections are more or less irregular and when the sash frames are swung into contact with the window frame, gaps exist between the adjacent irregular edgesor faces. As a result of such gaps weather strips are necessary in order I that the window be closed tight to prevent the passage of air and moisture.

The support for the weather strips may be bolted, welded, brazed or otherwise mounted on the metal frame. The present practice is to mount such sup orts in the field which, as is well known, entails much more labor and expense than when mounted in the shop.

One of the objects of my invention is to provide a combination bead and weather strip of the class described, which is adapted for mounting on either the window or sash frame in the shop, thereby eliminating the expensive and tedious'field work incidental to installing the weather strips onthe job.

The .weather strips are usually constructed of resilient or flexible material which adjusts itself to slight inrregularities in the surface of the frame with which it contacts.

The sash and window frames may be constructed of angle sections, T sections, Z bar sections or of any other desired-rolled structural steel sections. In rolling sections of the sizes usually adopted for window construction, it is found that such members are frequently so deformed or out of alignment that the flexibility of the ordinary weather stripping cannot compensate therefor. The invention contemplates a mounting for the weather strip which has suflicient resiliency to permit the strips to follow the general contour of the frames, while the resiliency inherent in the strips compensates for the minor irregularities.

Other further and more particular objects will become apparent as the specification proceeds and-will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims. a

Referring now to the accompanying drawin forming a part of this specification:

Fig. 1 is an elevational view of a window on which the devices of my invention are mounted Fig. 2 1s a section on the line 2-2 of Fig. 1 to a larger scale;

Fig. 3 is a section similar to the section shown in Fig. 2 and illustrating a modified form of the invention;

Fig. 4 is still another section similar to that shown in Fig.2 illustrating a further modification of the invention; and

Fig. 5 is a section similar to those shown in Figs. 2, 3 and 4 illustratin a weather strip having a mounting indepen ent of the glazingabead. I

eferring now more particularly to the drawings, the numeral 10 generally designates a window having the devices of my invention ,mounted thereon. The window 10 is provided with a frame 11 having a Z-sha-ped section-llin which a sash 12 is mounted. The sash 12 has a frame 13 constructed preferably of a T-section. The frame .of the window 10 and of the sash 12 sash is omitted, as not being an essential part of the invention.

In Fig. 2 the window sash is shown in 7 closed position with the flange of the T-section 13 in contact with the lower vertical leg of the Z-shaped section 11. lit is to be understood that the sash frame 13 upon opening will be moved to the left, as observed in Fig. 2. A metal head 17 is shown as mounted on the stem of the T-section 13. The head 1? may be fastened to the section 13 in either the shop or field by any desired means, such for example, as welding, brazing or by the use of clips and bolts or screws. A glass pane 14 is positioned in the space between the head 17 and the flange of the T-section 13 and is shown as held fixedly in position by putty 15.

A projection 18 extends laterally and downwardly from the top of the head 17. The lower end of the projection 18 is turned, as shown, to form a pocket 20in which a triangular weather strip 19 is mounted. The T-section 13 forming the sash frame and the Z-section 11 forming the window frame extend completely around the window, thereby forming the top and bottom portions as well as the vertical side portions. The head 17, the projection 18 and the pocket .20 are likewise provided to extend entirely around the sash 12. The strip 19 may be provided as a continuous stripmounted in the pocket 20, extending completely around the window and serving, when the sash is closed, to prevent any air or moisture from passing through the window opening. It is obvious that the strip 19 and the pocket 20 in which the strip 19 is mounted may be given any other desired cross-section.

The stem of the T-section 13 is shown as terminating short of the upper leg of the Z-section 11, while the lower portion of the flange of the T-section bears against the lower leg of the Z-section, thereby forming a stop limiting the amount of closure of the window frame. Since the structure or ornamental steel sections have slight irregularities in their surfaces and are not always exactly aligned, it is obvious that the stem of the T-section 13 will not fit the Z-bar section sufiiciently close to revent circulation of the air, and it is also 0 vious that if the fastening means for the weather strip is mounted in a straight line on the sash frame, the possible irregularities in the Z-section 11 will prevent the weather strip 19 from closely fitting the adjacent leg of the Z-section 11 at all pbints. The projection 18 is made suflicient- 1y thick to provide the necessary rigidity to hold the strip 19 against the window frame and yet is thin enough to be sufliciently flexible to permit the mounting 20 and the strip 19 to follow slight irregularities in the Z-bar section 11.

The section shown in Fig. 3 difiers from that shown in Fig. 2 in that a projection 23, extending from the bead 22, projects downwardly' between the end of the stem of the T-section 13 and the upper leg of the Z-secmeshes tion 11. This construction requires a greater length for the pro ection 23. than tor the proection 18 of Fig. 2.

The projection 23 terminates in a pocket the bead27 to form M a gutter 28 for the reception of moisture run- I ning from the window pane. A projection 29 extends downwardly and outwardly from the inner edge of the gutter 28. providing a pocket 30 in which a weather strip 31 is' mounted. This construction difiers from that previously shown in providing, in addition to the condensation gutter, for even greater resiliency of the various members.

In Fig. 5 still another embodiment of the invention is shown, wherein the glass pane 14 is provided with a head 33 which is separate and distinct from the weather strip mounting. The weather stip 36 is shown as contained in a triangular shaped pocket 35, supported by a projection 34, suitably fastened to the stem of the T-section 13 by any desired means such as brazing, welding or the like. As in the previously described embodiments, the cross-section of the pocket 35 and strip 36 may be given any other desired form.

Thus it will be seen that I have provided a mounting for weather strips in connection with metal frames for windows and doorways and'the like whichperforms the dual function of a resilient holder for the strip and a bead for the glass pane. The device is also adapted for additional use as a condensation gutter operative to carry oil the condensed moisture running from the window pane.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence do not wish to be understood as limiting myself to the exact form, construction,

arrangement and combination of parts here in shown and described, or uses mentioned.
